Rock climbing is great for shoulder strength ... but not so much for shoulder flexibility. We probably all know at least one person that can't even lift their arms all the way above their heads ... or maybe you are that person. Anyways, we sat down with Summit yoga instructor Bailey Parrish and had her run through some really quick shoulder stretches, perfect for climbers looking to open their shoulders to improve their climbing, or even if you're just looking to get your arms all the way above your head, because that's great, too.
